# SIDIX LoRA — Free & Open Source AI Agent

> *"Thinks, Learns & Creates."*

**SIDIX** is an autonomous AI agent that runs 100% locally — no per-query cost, no data leaves your server, no vendor lock-in.

This repository hosts the **LoRA adapter** fine-tuned on top of [Qwen/Qwen2.5-7B-Instruct](https://huggingface.co/Qwen/Qwen2.5-7B-Instruct) using QLoRA (4-bit NF4 quantization, Kaggle T4 GPU). It is the language-model component of the larger SIDIX agent system, which adds RAG, 48 tools, ReAct loop, semantic cache, and a continuous-learning growth loop on top.

🔗 **GitHub (full agent)**: [github.com/fahmiwol/sidix](https://github.com/fahmiwol/sidix)
🌐 **Live Demo (Free)**: [app.sidixlab.com](https://app.sidixlab.com)
📜 **License**: MIT
🏷️ **Latest version**: v2.1.4 (Vol 20-fu3, 2026-04-26)

## What's Different about SIDIX?

| Property | SIDIX | Closed-Vendor AI |
|---|---|---|
| Inference cost | **Free** (own GPU/CPU) | Per-token billing |
| Data egress | **Stays on your server** | Sent to vendor cloud |
| Open-source | ✅ MIT — adapter + agent + corpus | Closed |
| Self-hostable | ✅ End-to-end | ❌ |
| Vendor LLM API fallback | ❌ Never (`brain_qa` core has zero `openai`/`anthropic`/`google` imports) | N/A |
| Epistemic labeling | `[FACT] / [OPINION] / [SPECULATION] / [UNKNOWN]` on sensitive claims | Generic disclaimer |
| Growth loop | LoRA retrains nightly from corpus queue | Static snapshot |

The adapter alone gives you SIDIX's **voice and behavior**. For the full agent (RAG, tools, growth loop) clone the [GitHub repo](https://github.com/fahmiwol/sidix) — that ties this adapter into the orchestration layer.

## Quick Start

### A. Standalone (transformers + peft)

```python
from peft import PeftModel
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
import torch

bnb = BitsAndBytesConfig(
    load_in_4bit=True,
    bnb_4bit_compute_dtype=torch.float16,
    bnb_4bit_quant_type="nf4",
)
base = AutoModelForCausalLM.from_pretrained(
    "Qwen/Qwen2.5-7B-Instruct",
    quantization_config=bnb,
    device_map="auto",
)
model = PeftModel.from_pretrained(base, "Tiranyx/sidix-lora")
tok = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-7B-Instruct")

# SIDIX uses Qwen2.5 chat template + persona-flavored system prompt
messages = [
    {"role": "system", "content":
        "Kamu adalah SIDIX, AI agent yang jujur dan bersumber. "
        "Persona aktif: AYMAN (general/hangat). Jawab natural; untuk klaim "
        "fiqh/medis/data, beri label [FAKTA]/[OPINI]/[TIDAK TAHU] + sumber."},
    {"role": "user", "content": "Apa beda RAG sama fine-tuning untuk knowledge update?"},
]
text = tok.apply_chat_template(messages, tokenize=False, add_generation_prompt=True)
inputs = tok([text], return_tensors="pt").to(model.device)
out = model.generate(**inputs, max_new_tokens=512, temperature=0.7, do_sample=True)
print(tok.decode(out[0][inputs.input_ids.shape[1]:], skip_special_tokens=True))
```

### B. Via vLLM (Production)

```bash
vllm serve Qwen/Qwen2.5-7B-Instruct \
  --enable-lora \
  --lora-modules sidix=Tiranyx/sidix-lora \
  --max-lora-rank 64
```

### C. Full agent (RAG + tools + growth loop)

```bash
git clone https://github.com/fahmiwol/sidix && cd sidix
# Follow README — quick start ~5 min
```

## 5 Personas (LOCKED 2026-04-26)

SIDIX adapts voice, depth, and framing based on which persona is active. Each has a distinct way of speaking — not boilerplate variations of one prompt.

| Persona | Specialty | Pronoun cue | Example query |
|---|---|---|---|
| **UTZ** | Creative, visual, brainstorm | "aku" | *"Bantuin desain logo coffee shop yang feel warm + handcrafted"* |
| **ABOO** | Engineer, code review, debug | "gue" | *"Audit fungsi Python ini, ada race condition?"* |
| **OOMAR** | Strategist, business, decision | "saya" | *"Bandingkan strategi pricing freemium vs flat untuk SaaS B2B"* |
| **ALEY** | Researcher, fiqh, deep academic | "saya" | *"Hukum puasa di hari Senin Kamis menurut 4 mazhab?"* |
| **AYMAN** | General, warm chat, everyday | "halo" | *"Lagi galau soal pilihan karir, bisa ngobrol bareng?"* |

The agent layer (in [`fahmiwol/sidix`](https://github.com/fahmiwol/sidix)) auto-routes based on question signal, or honors manual selection.

## 48 Tools (Agent Layer)

The LoRA alone is a chat model. The agent layer wraps it with 48 active tools:

```
Knowledge:  search_corpus · read_chunk · list_sources · concept_graph
Web:        web_fetch · web_search · pdf_extract
Code:       code_sandbox · code_analyze · code_validate · project_map
Creative:   generate_copy · brand_kit · plan_campaign · generate_ads
Image:      text_to_image (SDXL self-hosted)
Meta:       self_inspect · orchestration_plan · muhasabah_refine · tadabbur_*
Growth:     prompt_optimizer · roadmap_* · workspace_* · learn_agent
Admin:      complexity_tier · domain_detect · semantic_cache_stats
```

ReAct picks the right tool per turn — see [`apps/brain_qa/brain_qa/agent_react.py`](https://github.com/fahmiwol/sidix/blob/main/apps/brain_qa/brain_qa/agent_react.py).

## Privacy & Security

- ✅ Zero data egress to external servers — all inference local
- ✅ No vendor LLM API key required — `brain_qa` core has zero `openai`/`anthropic`/`google` imports
- ✅ 4-label epistemic tagging — hallucinations get labeled, not hidden
- ✅ Identity masking — backbone provider names never confirmed/denied in user-facing output
- ✅ MIT License — free to use, modify, and redistribute

---

## Limitations & Honest Notes

- **Indonesian-first**: Best quality in Indonesian. English second, Arabic third.
- **Not a benchmark hero**: Optimized for *epistemic honesty* and *agent loops*, not MMLU/HumanEval leaderboards. We chose calibration over scores.
- **Sanad chains depend on corpus**: For fiqh/medis claims, quality of citation depends on the corpus you load. The default corpus emphasizes Islamic epistemology and AI research.
- **Adapter alone ≠ agent**: This repo is the LoRA. The 48-tool ReAct loop, RAG, growth loop, and semantic cache live in [`fahmiwol/sidix`](https://github.com/fahmiwol/sidix). Use them together for the full SIDIX experience.
